Distributed Computing Setup

On both machines Ensure you have the latest Simulator build installed.  It should be the same version on both machines. Use the RegSimAuto utility in the Simulator installation directory to ensure the correct version of Simulator is registered. On the remote machine Set up a user that will be used to run distributed computation.  This […]

Using Contingency Categories for monitoring of different voltage deviation limits for different contingencies

Previous knowledge base articles have covered both Monitoring voltages for Post Contingency Voltage Drop Criteria Monitoring which covered how to monitor all buses in the system for a particular voltage drop. How to specify different Voltage Deviation Limits for different buses in Contingency Analysis which did a similar thing but allowed the criteria to be […]

Can I solve a Real-Time power flow in Retriever?

Yes.  The data that is imported from the real-time sources can be substituted for the underlying system data to solve a real-time power flow in Retriever, provided that: a complete system model with all required object fields necessary to run a power flow solution is provided (see case validation), and the underlying model fields (when […]

I am getting $5000 / MW-hr LMP’s. Can that be correct?

If a constraint cannot be enforced due to insufficient controls, the slack variable associated with enforcing that constraint cannotbe removed from the LP basis.  Marginal cost depends on the arbitrary cost of the slack variable.  This value defaults to  $5000 per MW-hr in order to enforce the equality constraint that a control area’s generation should […]
